Drum coal mining device

Abstract

The invention discloses a drum type coal mining device. The drum type coal mining device comprises a shell, a first drum, a second drum, a reversing mechanism, a cutting driving mechanism and a driving mechanism, wherein a first transmission part and a second transmission part are arranged at the inner part of the shell; a guiding slide boot is arranged at the bottom part of the shell; the first drum and the second drum are used for cutting coal, are both arranged at the outer part of the shell and are respectively connected with the first transmission part and the second transmission part; the reversing mechanism can be connected into a containing cavity in a lifting way, and is arranged between the first transmission part and the second transmission part; the cutting driving mechanism is movably connected with the reversing mechanism through a driving part and can do reciprocating movement along the reversing mechanism so as to drive the first transmission part or the second transmission part to transmit; the driving mechanism comprises a guiding slide track and traction components; the shell is connected to the guiding slide track through the guiding slide boot; the traction components are used for drawing the guiding slide boot to do reciprocating movement along the guiding slide track. According to the drum type coal mining device provided by the invention, the problems that a thin coal seam is difficult to mine by using a drum type coal shearer, the mining time of the thin coal seam is long, the production is low and the like are solved.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a double-drum drum coal mining device suitable for thin coal seams. Background technique [0002] In recent years, with the improvement of mechanization, the reserves of thick coal seams and medium-thick coal seams in my country are decreasing day by day, or even exhausted. Therefore, the mining technology of thin coal seams must be paid attention to. Coal seams with a thickness below 1.3m in underground mining and coal seams with a thickness below 3.5m in open pit mining are thin coal seams. In my country, about 19% of coal seams are thin coal seams. [0003] In the traditional coal mining technology, the drum shearer is used to mine thin coal seams; the drum shearer is divided into single drum and double drum according to the number of working mechanisms, the latter is mostly used for thick coal seams and medium thick coal seams, and the former is mostly used for Thin coal...
